Description

The A6276EA and A6276ELW are specifically designed for LED- display applications.  Each BiCMOS device includes a 16-bit  CMOS shift register, accompanying data latches, and 16 npn constant-current sink drivers.  Except for package style and allowable package power dissipation, the A6276EA and A6276ELW are identical.

The CMOS shift register and latches A6276EA and A6276ELW allow direct interfacing with microprocessor-based systems.  With a 5 V logic supply, typical serial data-input rates are up to 20 MHz.  The LED drive current is determined by the user's selection of a single resistor.  A CMOS serial data output of A6276EA and A6276ELW permits cascade connections in applications requiring additional drive lines.  For inter-digit blanking, all output drivers can be disabled with an ENABLE input high.  Similar 8-bit devices are available as the A6275EA and A6275ELW.

Two package styles of A6276EA and A6276ELW are provided for through-hole DIP (suffix A) or surface-mount SOIC (suffix LW).  Under normal applications, a copper lead frame and low logic-power dissipation allow the dual in-line package to sink maximum rated current through all outputs continu- ously over the operating temperature range (90 mA, 0.75 V drop, +85°C).  Both A6276EA and A6276ELW are also available for operation over the standard temperature range of -20°C to +85°C.  To order, change the suffix letter 'E' to 'S'.
